[compiler-rt][cmake][mips] Correct the option handling for GCC 7

Authored by atanasyan on May 8 2018, 5:02 AM.



GCC 7 rejects the usage of --target=mipsel-linux-gnu, which earlier versions
accepted but warned on. Instead, detect the compiler being used and supply
--target=mipsel-linux-gnu for Clang only.

Additionally, -mips32r2 requires -mabi=32 for versions of GCC which target
mips64 by default.

This resolves PR37002.

Thanks to James Cowgill for reporting the issue!
